Description

Technical Field

[0001] This utility model relates to the field of DLC coated cutting tool technology, specifically a DLC coated cutting tool. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. During the production and processing of cutting tools, other materials are often used to form a DLC coating on the surface of the cutting tool to increase its hardness, wear resistance, etc.

[0003] Existing machine tool cutting tools generally consist of a tool holder mounted on the machine tool and a tool shank used to fix the cutting head. The tool holder and tool shank are fixed by multiple sets of fastening bolts. Since the cutting head needs to be replaced when it wears out during use, multiple sets of fastening bolts need to be disassembled one by one, which is a rather cumbersome process. To address this, we propose a DLC-coated cutting tool that uses a gear set to drive a drive rod to rotate two sets of bolts, thereby fixing and disassembling the tool shank, making the assembly and disassembly much simpler. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a DLC-coated cutting tool, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a DLC-coated cutting tool, comprising:

[0006] Tool holder, the tool holder being mounted on a CNC machine tool;

[0007] A tool holder, wherein the tool holder is installed at the lower part of the tool shank, and the lower part of the tool holder is the tool tip end;

[0008] Bolts, the two sets of bolts having threads that penetrate the tool holder and the tool shank;

[0009] The outer frame is rotatably connected to the outside of one end of two sets of bolts;

[0010] A drive rod, which is rotatably connected to the middle section of the outer frame;

[0011] The gear set is sleeved outside the drive rod and two sets of bolts, and the gear set is located inside the outer frame.

[0012] Furthermore, the DLC-coated tool also includes:

[0013] The brackets, two sets of which are fixed to both sides of the outer frame;

[0014] Guide plates, the two sets of guide plates are fixed to the sides of the two sets of brackets.

[0015] Furthermore, the DLC-coated tool also includes:

[0016] The first set of four screw holes is located on the side wall of the tool holder, and the two sets of bolts are threaded into the interior of the first set of four screw holes.

[0017] Furthermore, the DLC-coated tool also includes:

[0018] The guide grooves are symmetrically arranged on both sides of the tool holder, and the two sets of guide plates slide inside the two sets of guide grooves respectively.

[0019] Furthermore, the DLC-coated tool also includes:

[0020] Two sets of screw holes are formed on the upper part of the tool holder, and two sets of bolts are threadedly connected inside the two sets of screw holes.

[0021] Furthermore, the gear set includes:

[0022] A drive gear, which is sleeved on the outside of the drive rod;

[0023] Driven gears, two sets of driven gears are sleeved on the outside of two sets of bolts, the two sets of driven gears are located on both sides of the driving gear, and the driving gear and the two sets of driven gears are meshed.

[0024] Compared to the aforementioned background technology, the DLC-coated cutting tool provided in this application includes a tool holder, a tool shank, bolts, an outer frame, a drive rod, a gear set, a bracket, and a guide plate. The gear set enables the drive rod to move two sets of bolts, achieving simultaneous disassembly of the two sets of bolts. Compared to the traditional method of disassembling multiple sets of fastening bolts sequentially, assembly and disassembly are much simpler.

[0025] This invention provides a DLC-coated cutting tool. Compared with the prior art, it has the following advantages:

[0026] A DLC-coated cutting tool uses a gear set to drive a drive rod to rotate two sets of bolts in the same direction, causing the threads of the two sets of bolts to pass through four sets of threaded holes and two sets of threaded holes, thereby assembling and fixing the tool holder and tool shank. Alternatively, the free ends of the two sets of bolts can move into the two sets of threaded holes on one side of the outer frame, thereby contacting and fixing the tool shank. This structure allows for quick assembly and disassembly of the tool holder and tool shank, and is relatively convenient to operate. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-6 This utility model provides a DLC-coated cutting tool technical solution: a DLC-coated cutting tool, including a tool holder 1, a tool bar 2, a bolt 3, an outer frame 4, a drive rod 5, a gear set 6, a bracket 7, and a guide plate 8. Specifically, the tool holder 1 has four sets of screw holes 11 and two sets of guide grooves 12, and the tool bar 2 has two sets of screw holes 21. The four sets of screw holes 11 and the two sets of screw holes 21 are respectively adapted to the thread structure of the two sets of bolts 3.

[0036] After the upper part of the tool holder 2 is installed inside the tool shank 1, the drive rod 5 drives the two sets of bolts 3 to rotate in the same direction through the gear set 6. This causes the threads of the two sets of bolts 3 to pass through the four sets of screw holes 11 and the two sets of screw holes 21, thereby assembling and fixing the tool shank 1 and the tool holder 2. This allows the upper part of the tool holder 1 to be installed on the CNC machine tool. When the tool head is worn and the tool holder 2 needs to be disassembled, the drive rod 5 drives the two sets of bolts 3 to rotate through the gear set 6. This causes the free ends of the two sets of bolts 3 to move into the two sets of screw holes 11 on one side of the outer frame 4, thereby contacting the fixation of the tool holder 2 and allowing for replacement.

[0037] As the two sets of bolts 3 move, the outer frame 4 moves accordingly and slides within the two sets of guide grooves 12 via the two sets of guide plates 8, making the movement of the two sets of bolts 3 and the outer frame 4 more stable.

[0038] The gear set 6 includes a driving gear 61 and driven gears 62. Specifically, the driving gear 61 is sleeved on the outside of the drive rod 5, and the two driven gears 62 are sleeved on the outside of the two bolts 3. When the driving gear 61 rotates, it can drive the two driven gears 62 to rotate synchronously in the same direction, thereby driving the two bolts 3 to rotate synchronously in the same direction.

[0039] In actual use, the upper part of the tool holder 2 is first installed inside the tool handle 1. Then, the drive rod 5 is driven by the gear set 6 to rotate the two sets of bolts 3 in the same direction, so that the threads of the two sets of bolts 3 pass through the four sets of screw holes 11 and the two sets of screw holes 21, thereby realizing the assembly and fixation of the tool handle 1 and the tool holder 2.

[0040] When the cutter head is worn and the cutter bar 2 needs to be disassembled, the gear set 6 causes the drive rod 5 to rotate the two sets of bolts 3, so that the free ends of the two sets of bolts 3 move into the two sets of screw holes 11 on one side of the outer frame 4, thereby contacting the fixing of the cutter bar 2, and thus replacing it.
